SEWING MACHINE Filed March 3, 1936 4 Sheets-Sheet 4 v Patented Jan. 9, 1940 UNITED` STATES' PATsNToFFicE I i SEWING MACHINE Joseph Gouldbourn and `Thomas Aubrey Kestell, Leicester, England, assigner-s to United Shoe Machinery Corporation, Borough `of Flemington, N. J., a corporation of New Jersey 'Application March 3, 1936, Serial No. 66,830 ,l In Great Britain March 8, 1935 s omnes. (o1. 11a- 62) l have an external worksupport presenting two work-supporting faces `extending vat right angles to each other to support the twoparts to be sewn together (one of said faces for example extending forwardly' and upwardly at about forty ve degrees to the horizontal and thevother extending forwardly and downwardly at the sameangle) and a depending work-entering horn which is arranged to press the two parts of ythe work against the facesof the work-support, the horn having viand,rearwardly, .at about forty-live degrees ,to the a 'bowed shape vand presenting at its lower enda workentering portion which extends rearwardly and downwardly towards the junction of the two faces of the work-support and being arranged for lateral swinging movement, duringrthe workr engaging portion of the horn and extends upv wardly at a substantial angle to both of the faces of the work-support, e. g. the ,said axis lying perpendicularly to a line bisectingtheanglebet veen the faces wheny the machine is looked at from the side i. e. along the line ofk work feed,

Horns of this `kind mounted in the manner indicated have proved able inpractice to support and control adequately work of various kinds to allow the parts to be sewn firmly together but nevertheless the relation-,above indicated, to the work-supporting faces ofthe work support, of the f work-entering portions of such horns andthe fact that thev horns are mounted to ,swing about laxes which extend at a substantial angle to `the twov faces of the work-support occasionally present difficulties in the sewing together of parts of cases which have but small mouths, particularlycases,

such as camera cases and music cases, 'which aref relatively deep and relativelynarrow from front to rear. This is largely because the swinging movements of the horn which are necessary, in sewing a side into a case, to allow the sewing to progress from the open mouth along one side corner of the case, around the closed end thereof and along the other side corner towards the i open mouth tend to cause the work-entering portion of the horn, in its swinging movementsyto strike against the front wall of a relatively narrow case and prevent the continuance `of the sewing together of the two parts to be'joined. k

One of theseveral objects of the present invention is to overcome this disadvantage by providing ahorn which will give efficient control of the work and can enter'readily into va narrow case and, inspite ofthe fact. that it may be swung from side to side as required during the c.

sewing operation, will not cause the portion thereof extending into the case to move in such a Amanner as to obstruct the completionof ythe sewing operation on the case.

`In a particular illustrative yembodiment of the y present invention hereinafter more particularly described a rotaryhorn is mounted to swing laterally aboutan axis which, instead of extending at a vsubstantial angleto both the faces of the work-support, is arranged parallel.. or at least almost parallel, to the lower downwardly and forwardly extending face of the external support (i. e. is arranged at an angle extending upwardly horizontal)` and the work-entering portion of the horn is bowed at such an angle to itsv main portionthat it lies perpendicularly to the axis just mentioned, that is, it lies parallel, or almost parallel tothe upwardly rand forwardly sloping v face ofthe external support. The said work- 'entering portion is spaced far enough forwardly of this face of the supportas to allow the mountingon` it, coaxially with said axis, of a substantially cylindrical work-engaging roll, the peripheral and rearward end facesv of which 'are arvranged to press the two parts to be sewn togetheragainst the respective faces of the worksupport. y y

, By .arranging forthe hornto swing about an axis inclined as above indicated, it will be appreciated thatthe horn maybe swung through one hundred and eighty degreesfrom a position extending towards the left into a positiontextending ytowards the right without causing its work-enteringportion to deviate out of its parextendingface ofthe work-support, cases or the like which are but just wide enough at the mouth to allow the horn to enter into them can be sewn -bythe machine sincev the `wc` rlsentering portion of the horn will not move forwardly or rearwardly, at least to any measurable extent, in the case and will not therefore be likely to strike against its forward or rearward sides.

In order that the various objects and the several features of the present invention (which latter are hereinafter set forth in the appended claims) may be more clearly understood, the illustrative embodiment aforementioned will now be described with reference to the accompanying drawings.

In the drawings:

Figure 2 is a view similar to Figure 1 on a somewhat larger scale;

Figure 3 is a plan view of certain parts of the machine;

Figure 5 is a detail sectional view on the line 5-5 of Figure 2; and

Figure 6 is a detail sectional view of certain of the parts for supporting the horn of the machine.

The machine illustrated in the drawings is of the type disclosed in the specifications of British Letters Patent Nos. 430,934 and 415,480, corresponding respectively to U. S. application of Gouldbourn and Kestell No. 749,594, filed October 23, 1934, and U. S. patent to Gouldbourn No. 2,029,099, dated January 28, 1936. Like the machine disclosed in said patents and application, the illustrated machine has an external work support with angularly disposed work engaging surfaces, a bag entering horn provided with a work support to engage the work internally, a horn actuating and controlling mechanism, and means for effecting conjoint angular adjustment of the horn and external work support. The illustrated machine may be provided with a horn constructed and arranged as in U. S. patent to Gouldbourn above referred-to. Such a horn is indicated in dot-and-dash lines at 3 in Figures 1 and 2, being mounted in a horn supporting mechanism which is similar in all respects to that disclosed in the Gouldbourn patent. This horn supporting mechanism is detachably secured by two vertical bolts, one of which is indicated at 8, to a block 4 mounted upon pivot pins 'I at the forward end of a carrier similar to that disclosed inthe U. S. patent to Gouldbourn, and comprising a pair of horizontally arranged arms 2l supported by a pair of vertically arranged yokes 23 and 25. As in the machine of the U. S. patent to Gouldbourn, the yoke 23 is adjustable about a fixed shaft 21, and the yoke 25 is adjustable about the shaft I 9, an adjustment of these yokes acting to vary the angular position of the horn with relation to the external work support I. The yokes and carrier are locked in adjusted position by means of a clamping handle Il screw threaded upon the outer end of the shaft I9.

The machine provided with a horn constructed and arranged in this manner has been found, in practice, to give admirable results in sewing suitcases of certain kinds and other relatively large articles. To adapt the machine for sewing together the parts of cases which have but small supporting an alternative arrangement of horn which can be used with advantage when it is desired to use the machine for sewing together parts of relatively narrow and deep cases. For supporting this alternative arrangement of horn, the illustrated machine is provided with a bracket I3, the forward end portion of which is bifurcated and pivotally mounted on the pins l. Rearwardly of its forward end the bracket I3 is provided with a depending web I5 having in it a slot IT through which the shaft I9, on which the clamping handle II is mounted, passes. The bracket I3 is thus supported at its forward end by the pins 'I on the carrier arms 2I and is supported at its rear end by the shaft I9. The portion of the yoke 25 surrounding the shaft I9 is split, as best shown in Fig. 5, and the web I5 on the bracket I3`is received between the split portions so that an actuation of the clamping handle II serves to clamp the yoke 25 and the web I5 in xed position against one of the upstanding ears 29 of the machine frame through which the shaft I9 passes and between which the yoke 25 and web I5 are located. By Areason of the slotted engagement of the web I5 with the shaft I9, a movement of the yokes 23 and 25 to adjust the position of the horn carrier arms 2i produces a corresponding adjustment of the bracket The alternative arrangement of the horn is arranged to be supported by the bracket I3 and comprises a somewhat tubular casting 3|, forming a housing for a sleeve 33 supporting a horn spindle 35. The casting 3| is arranged to extend upwardly and rearwardly at such an angle and at such a heightwise position inthe machine, that the axis of the horn spindle 35 lies substantially parallel to the forwardly and downwardly extending face` 3l of the external work-support (i. e., the axis extends upwardly and rearwardly at an angle of some forty-five degrees to the horizontal) and extends a short distance, e. g., one vhalf of an inch, above that surface when positioned to operate on work of an average thickness.

In order to support the casting SI in this position, and allow it to be actuated to move the work engaging portion of the horn towards and from the external Work support during each stitch formation, the bracket has a pair of rods 39 and 4I passing laterally between flanges depending from its left and right hand sides. A yoke 43 is freely mounted on the rod 39 and its lower ends embrace the opposite sides of the casting 3l and are connected to it by pins 45 arranged parallel tothe rod 39. A second yoke is mounted on the rod 4I and has an arm 4l depending from it which is connected by a pin ,49 to ears extending from the forward side of the casting 3|. The yoke 43 and the arm 4l' are equal in length but are not quite parallel to each other, the arm 41 being slightly more nearly vertical so that, when the arm lll is rocked about the rod III through a small angle by' means hereinafter described, the result vwill be to cause the work-engaging portion of the horn supported by the horn spindle 35 to move in an arc substantially concentric about the pins 1, i. e., the said work-engaging portion of the horn will move about substantially the same axis as the horn 3.

The sleeve 33 is appreciably smaller in diameter than the bore in the casting 3l and is supported within the latter by two co-axial pins 5I threaded in the sleeve and extending forwardly and rear- Wardly of the machine perpendicularly to the is secured against endwise movement within the sleeve 33 but is free to rotate therein, ball bearings being provided at the opposite ends of the sleeve to facilitate the rotary movement of the" spindle. At its upper end the spindle carries a head 53 through which is formed a bore extendin'g at right angles to the axis of the spindle, The rear end of the horn proper, which latter is indicated at 55, enters' into this bore and is clamped in it by clamping screws which pass through splitportions of the head. From its rear end the horn is rst bowed upwardly to clear adjacent parts of the machine and is then enclined forwardly and downwardly and nally is turned rearwardly and'downwardly to provide a.

i The horn is formed of a metal tube strengthened against .bending by Webs 6l, 53 welded on the horn.- In order to prevent the weight of the forwardly of the upwardly and forwardly extending face 59 of the work-support and its lower end is ilattened. (it beingv conveniently some half an inch in width) and has projecting through it a short stud 13, the axis of which is co-.axial with that of the horn-carrying spindle 35.r A substantially cylindrical roll 15 some ve eighths of an inch in diameter so as just to extend beyond the end and sides of the flattened end of the horn, is freely rotatable on the stud 13 and its peripheral face is arranged to pressl one of the parts'being sewn together against the downwardly and for-- wardly extending face 31 of the external support while the rear end. face of the roll is arranged to press the other part of .tlfre work against the forwardly and upwardly extending face 53 of the work-support, the angle between the peripheral face of the roll and its rear endface being bevelled oif to facilitate the passage'of the needle 'i1 and the awl 19 'through the wor without obstruction by the roll.

Like the machine disclosedvin the U, S. lpatent to Gouldbourn above referred to, the machine of the present' illustrative embodiment `has a cam-actuated lever 8l, a rod 83, a bell crank lever land a rod 81 and' spring. 39 interconnecting the lever 85 with an arm 50h the block i for urging the horn 5 rmly against the work during each cycle of the machine and for relieving the pressure of the horn on the work when the awl is acting to feed the work. This mechanism is made use of in the present illustrative machine for moving they casting 3l in such amanner that the roll 15 will" move towards the work somewhat to' press firmly on it when 4desired' and will move away from it somewhat at the desired time to relieve its presl directly tofrockabout the pins 1. For this purpose the yoke carrying the arm '41 carriesa second arm 9! lying lby the side of the varm 41 and a rod 93 connects the arm 9i with the arm 5, the lower end of the rod lying within a slot formed inthe arm 5 and being connected to the latter by a readily removable-pin 55. The arm 5 will bev given slight rocking movements about the pins 1, during the operation of the machine, through its connections with the lever l, and the arm t will therefore impart slight rocking movements to thearm 41 about the rod lll and will thus cause the casting 3! and the horn 55 supported thereby to move in such a path, controlled by the arms d3, 41, that the roll 15 will. move along a path substantially concentric about the pins Tand willthus apply increased pressure evenly to. or relieve .the pressure evenly from both parts of the work engaging the faces 31, 59 of the work support. f

ByV supporting the horn 55 in the casting 3l and mounting the latter on the arms 53, 41, the nature ofthe movement imparted to the roll 15 approximates to that it would have if the casting .3l were mounted to pivot about the pins 1,. but the extent of. the bodily movement of the casting 3| necessary to impart a given movement to theroll 15 is much smaller with the present arrangement. Further the weight of parts to be moved is less, with ther present illustrative construction, than would be likely to be the case if the casting were carried by an arm pivoted to rock on `the pins y1. This is particularly so since the balance weight 1l hereinbefore referred to is arranged and connected to the horn 'bearinginV such a manner that the movements oi` the latterdo not bring about equal movements of the balance weight. These facts facilitate the actuation of the horn 55 by the cam-actuated lever 8! andv the spring 89 and obviate what might otherwise ce a marked tendency, due to the factthat this horn extends so far. rearwardly Vof the sewing point from'the roll 15 to the spindle 3,5, for the hornto be somewhat sluggish inaction. l j

Means is yprovided whereby the roll. 15 may be adjusted in position towardsy or away vfrom the face 31 of the external support to take care of work in which the part of the workengaging that y .diametrically from the fact previously mentioned vand this spring urges the rod in a counterclock- -wise direction to maintain the virst mentioned.

face in contactwith the end of the stud 91. By

rotating the stud in appropriate direction, the rod` 4I, may be rotated in a' clockwise direction, as seen from the right, and will thus cause the arm 41 to move downwardly somewhat. This will result in the casting 3l pivoting somewhat about the pins 45 .and therefore will result in the roll 15 moving downwardly towards the face 31 of the work support I. By rotating the stud 91 in the reverse direction, the spring 95y will causel the arm 41. to vrise-somewhat and thus. cause the roll to rise away' from' the face 31 oi the work support. To facilitate the accurate positioning of the rear end of the horn within the head 53, there is threaded axially into this end of the horn, which has a sleeve fixed to it, a stop screw |ll| which is adapted, when the horn has been inserted into the head, the correct distance, to abut against the pin 66 aforementioned and thus to prevent the horn from being pushed further into the head.

The pin t5 which couples the arm 5 to the rod 93 is, as before stated, a readily removable pin, it being a push pin adapted to be inserted throughl holes in the slotted portion of the arm 5 and in the lower end of the rod 93. When it is desired i. to use the horn 3, for example when it is desired to oier relatively large cases to the machine, instead of the horn 55, the latter may be withdrawn from the head 53 and the pin 95 pulled out of the holes in the arm 5 and the rod 93, the horn 3 being then assembled on the machine. Removal of the pin 95 disconnects the casting 3| from the cam actuated lever 8| and in order then to prevent idle movement of the casting 3| during operation of the machine, the yoke carrying the arms 41 and 9| 'carries a third arm |03 to the lower end of which is coupled the forward end of a tension spring |05, the rear end of which is xed to the bracket |3. The spring |93 therefore acts to hold the casting 3| in an upward position which is determined by contact between the lower end of a set screw |01 threaded downwardly through the bracket |3 and a fourth arm |09 carried by the yoke last mentioned.

Like the machine disclosed in the U. S. patent to Gouldbourn above referred to, the machine of the present illustrative embodiment is` provided with a treadle for swinging the horn forwardly to facilitate the introduction on to and removal of work from the horn and external work support For this purpose the arm 5 is connected by a link to an arm ||3 pivotally mounted at its rear end on the machine frame. The upper end of a toggle link ||5 is pivotally connected to an ear depending from the arm |3 and the lower end of this link is pivoted to the upper end of a second toggle link ||1, the lower end of which is mounted in a fixed pivot. The upper link ||5 has a rearwardly extending ear to which is connected, conveniently by a pin passing through a hole of slightly larger diameter, the upper end of a treadle rod |9. A relatively long tension spring 2| is connected at its forward end to the point of connection between the toggle links ||5, l I1 and at its rear end to the machine frame and thus tends to straighten the links and lift the arm i3 to maintain the roll 15 pressingy against the work, a stop on the treadle rod being preferably provided to limit this action of the spring. A downward pull on the treadle rod elected through a treadle on its lower end will cause the toggles to break forwardly against the action of the spring |2| and thus to rock the arm 5 downwardly and to withdraw from the work whichever of the two horns may be in use at any time. The toggle connection between the treadle rod and the arm ||3 ensures that the horn may be swung away from the work without it being necessary for the operator to exercise any severe effort in depressing the treadle.

Similarly to the external work support described in the U. S. patent to Gouldbourn above referred to, the external work support of the present illustrative machine is pivotally mounted on vertically adjustable brackets |23 and the Work support and the brackets are coupled, through a heightwise adjustable rod |25 and vertically adjustable sleeves |21 carrying the bracket |23, to the forward yoke 23 of the two which carry the arms 2| by which the horn 3 is supported so that, as these yokes are swung forwardly or rearwardly to cause the horn to cant upwardly or downwardly, the external support is automatically and simultaneously canted, as more particularly described in the patent above mentioned, to a like extent in the same direction to maintain the work-engaging faces of the horn and work-support always; in the same relation to each other so that the work will be supported between them with equal eiciency at whatever angle it is presented to the needle and awl for the sewing operation. From a consideration of the Gouldbourn patent, it will be appreciated that the horn and external support both cant, during their adjustment, about a virtual pivot situated on the lower face of the lower frusto conical Work engaging roll carried by the horn 3. The slot |1 in the web I5 of the bracket I3 is formed concentrically about this virtual pivot and since the bracket is pivoted on the pins 1 at its forward end, angular adjustment in the positions of the yokes 23 and 25 will cause the bracket to move bodily in an arc concentric about the virtual pivot and, since the external work support will simultaneously be canted about the same pivot, the roll 15 on the horn 55 and the two faces of the external support will maintain their relation during the angular adjustment imparted to them through the yokes 23, 25.

From what has been said above, it will be understood that the present illustrative machine has a horn arrangement similar, in its mounting, construction and in its operation an-d coupling to the external support, to that described in U. S. patent to Gouldbourn above referred to, and further that the horn 3 of this horn arrangement is readily detachable from the machine (leaving its operating mechanism and coupling to the external support intact) and that the carrier for this horn supports a horn bearing 3| for an alternative horn 55, the work-entering portion of which, when looked at from the side of the machine, extends substantiallyr parallel to the forwardly and upwardly sloping face 59 of the work-support and the axis of the spindle 35 about which the horn 55 is swung from side to side during the sewing operation lying substan-l tially parallel to the forwardly and downwardly extending face 31 of the work-support. It will further be understood that the axis of the roll 15 lies on the axis of the spindle 35 so that, as the horn is swung from side to `side about the latter axis, the roll will have no bodily movement relatively to the work.

When the horn has been assembled in the machine and assuming that a case, indicated at X in Figure 1, having a relatively deep body and a relatively small mouth is to be sewn by the machine, the horn will be swung to the left about the axis of its spindle 35 into such a position that its work-entering portion 51 extends purely widthwise of the machine, it then also lying, by reason of the fact that this portion lies perpendicularly to the axis of the spindle 35, purely horizontally. The operator then depresses the treadle connected to the horn to draw the horn forwardly somewhat to allow the parts of the case to be placed on the work-support after which he releases the treadle and the horn is then urged rearwardy under the action of the springs 89 and (2l to press the vtwo parts ofthe work against the two faces of the support. The machine is then started into operation and the sewing proceeds along one side corner of the case towards the closed bottom. As the sewing proout danger of the parts` of the work being obstructed by the horn. ,'W'hen` the sewing has proceeded along the side of the case and has reached the end, the operator proceeds toturn the case upwardly on its end towards the position indicated in Figure 1, to allow -the sewing to proceed therearound and, as the case is so turned, the work-entering portion of` the horn will be carried round with the` case, remaining asitv does so substantially parallelt-o the upwardly and forwardly sloping face of the work-support and therefore to ther part of the work lying against this face.

will have little, or no, bodily forward or rearward movement within the case and will not, therefore, be likely to strike against the forward or rearward parts of the case nor obstruct the` does so, the horn will swing in company with it.

When the sewing actually commences along the second side corner towards the openmouth, the case will have been turned through 180 degrees from its initial position and the horn-will likewise have been turned through the same angle and its work-entering portion then extends horizontally towards the right from its work-engaging roll. The sewing along this second side cornerl can, therefore, be carried out up to the mouth of the case, the case being meanwhile fed off the work-entering portion of the horn, without the horn obstructing this movement by fouling any part of the work.

As in the case in the horn arrangement described in the U. S. patent to Gouldbourn above referred to, the horn 55 is supported in a pendulous manner about the pins I on which its supporting sleeve 33 is pivoted sothat'the workengaging portion of the horn may be urged along the line of feed, towards the left or right, out of its normal position to' enable a stitch to be sewn in the work close to an upstanding end wall of the work lying at the right or left hand side of the horn. In order to maintain the roll 15 on the horn normally in a constant position to which it is carried by the action on it of the moving work, the tubular casting 3l has extending hori- Zontally through it, at its right-hand side and near its upper end, i. e., above the pins 5I a threaded sleeve in which is housed a springpressed plunger |29 which is adapted to bear against the right-hand side of the sleeve 33. By forcing an upstanding wall of the work at -the right-hand side of the horn againstthe workengaging roll l5 thev latter can be moved towards the left along the line of feed, against the action of the spring-pressed plunger, to a1 r Therefore, as the case is so turned, the work-entering portion of the horn,-

low this wall to approach closer to the needle plane for the purpose indicated. In order to limit movement of the work-engaging roll in the opposite direction, an adjustable screw is threaded through the left-hand side of the'casting 3| to abut against the left-hand side of the latter -when the roll has been swung to its 'limit towards the right of the machine. l
